Description

FIELD

The present invention relates to the field of clearing tools, and in particular to a shovel handle connecting device.

BACKGROUND

A shovel is used as a tool for picking up or clearing material, a general shovel includes a shovel handle and a shovel scoop connected to the shovel handle, wherein the shovel handle is configured to be held and the shovel scoop is configured to pick up or clear material. For a common shovel in the market, generally, a shovel handle is fixedly connected to a shovel scoop through threaded fit connection. The above-mentioned mode has the following defects: after used for a long time, the shovel is prone to looseness and the connection is not stable enough.

SUMMARY

In order to overcome the defects in the prior art, the present invention provides a shovel handle connecting device in which the connection is stable and not prone to looseness.

To realize the objective, the present invention uses a technical solution as follows: a shovel handle connecting device includes a connecting assembly configured to connect a shovel handle and a shovel scoop, wherein the connecting assembly includes a connecting member and a connecting seat; a front end of the connecting member is provided with a connecting portion and a limiting portion, a limiting fastener is arranged on the connecting portion, and the connecting seat is embedded in the shovel scoop; the connecting seat is internally provided with a connecting groove allowing the connecting portion to be inserted therein, and an inner wall of the connecting groove is provided with a limiting groove allowing the limiting fastener to be snapped therein; the connecting member is inserted and fixed in the connecting seat; and one section of an outer side wall of the limiting portion and one section of an inner side wall of the connecting seat are formed into an accommodating cavity in an enclosure mode, and one end of the shovel handle is inserted and fixed in the accommodating cavity.

For using the shovel handle connecting device, firstly, the connecting seat is embedded in the shovel scoop in advance to form an integrally-formed structure with the shovel scoop. The connecting portion of the connecting member is inserted into the connecting groove of the connecting seat in an alignment mode, after the connecting portion is inserted into an exact position, the connecting member and the connecting seat are fixedly connected through the snap connection between the limiting fastener and the limiting groove, and after the connection, the limiting portion of the connecting member and the connecting groove of the connecting seat are formed into one section of the accommodating cavity at an inlet end, and the shovel handle is inserted into the accommodating cavity to realize the fixed connection between the shovel handle and the connecting member as well as the connecting seat. After the above-mentioned solution is used, the stable connection between the connecting member and the connecting seat is realized through the cooperation between the limiting fastener and the limiting groove, and therefore, the connection between the shovel handle and the shovel scoop is stable and is not prone to looseness.

As a further improvement, the limiting fastener is provided with a first oblique surface obliquely arranged from front to back; the limiting groove is externally provided with a second oblique surface matching the first oblique surface and configured to guide the limiting fastener to slide into the limiting groove; and the limiting groove is internally provided with a third oblique surface capable of being attached to the first oblique surface. After the above-mentioned solution is used, through the arrangement of the first oblique surface, when the connecting member is inserted into the connecting seat, the first oblique surface is pressed, the limiting fastener can be smoothly snapped into the limiting groove, and therefore, the insertion is convenient and easy to implement. Through the arrangement of the second oblique surface, the limiting fastener may be guided to slide into the limiting groove. Through the arrangement of the third oblique surface, the limiting fastener and the limiting groove may be in close fit to reduce the wear to the first oblique surface.

As a further improvement, the limiting fasteners are distributed in a spaced mode in an axial direction of the connecting member to form a zigzag snap, the limiting grooves are distributed in a spaced mode in an axial direction of the connecting seat to form a zigzag snap groove, and thus the connecting member and the connecting seat are fixedly connected by means of the meshing snap connection between the limiting fasteners and the limiting grooves. The zigzag design makes the connection between the connecting seat and the connecting member stabler and firmer.

As a further improvement, the shovel handle and the connecting member are fixedly connected through a rivet at an insertion position. By using the rivet for the fixation, a structure is simple and a cost is low, and after the fixation, the handle may be effectively prevented from deflecting around an axis in the use process.

As a further improvement, the limiting fastener is arranged at the bottom of the connecting portion, and the top of the connecting portion is provided with a reinforcing plate. Through the design of the reinforcing plate, the strength of the connecting portion is enhanced, and the shovel can bear a large external force in the use process.

As a further improvement, the top of the connecting seat uses a curved surface structure in which two ends are upwards tilted and a middle is horizontally dented. By using the above-mentioned structure, the connecting seat can be well embedded in the shovel scoop and will not be loosened in the use process.
